As a result, $5.3 billion in diesel cars are now sitting, unsold, on dealership lots, some as new as the 2015 model year. This number is likely to grow, as a sample poll of German diesel owners found that 29% planned to sell their cars as soon as possible, as their values have continued to plummet and more diesel bans are put into place.

The build up isn’t particularly helped by the automakers, as several have launched buyback programs, offering up to $8,250 toward a new, presumably compliant diesel car. Apparently, the collected cars will mostly be scrapped.

So, used car dealerships are stuck waiting, sitting on a hill of used diesel vehicles and watching to see if their inventory will be banned.
